PRE-TREATMENT In-ground Fiberglass Pit Systems Optional Diamond Plate Aluminum Covers Catch Basin Water Maze offers in-ground fiberglass pits, which are easy to install at the job site. As compared to poured-in-place concrete pits that may eventually crack and allow water to leach into the ground, our fiberglass pits immersed into concrete can provide double containment. We offer three sizes of pits. The In-ground Separator (IGS) is uniquely designed with two sets of standing weirs that force solids to the bottom of the pit.
